Application November 9, 1953, Serial No. 390,840

3 Claims. (Cl. 240-148) This invention relates to lamps and is directed particularly to a device for mounting a lamp shade on the mounting frame or harp of a lamp.

In appllicants co-pending application Serial No. 174,987 filed July 20, 1950, now United States Letters Patent No. 2,658,990, issued November 10, 1953, there is disclosed an improved device for tiltably mounting a lamp shade on a lamp base. The present invention provides an improved non-tiltable, non-rotatable lamp mounting means comprising the harp with which, nevertheless, lamp shades of the type shown in the co-pending application as well as those of a similar type described herein may be used.

It is the principal object of the invention to provide a rigid, simple and efiicient means for mounting a lamp shade on a harp so that it is non-rotatable and nontiltable.

It is another object to provide a shade mounting device of the character described the componant parts of which can readily be manufactured by screw-machine and punch-press operations, and which parts are easily assembled.

With these and other objects and advantages in view, this invention consists in the several novel features hereinafter fully set forth and more particularly defined in the appended claims.

In the drawings, wherein like reference numerals denote corresponding parts throughout the several views;

Fig. l is a front elevation of a lamp and lamp shade embodying the invention, a portion of the shade being cut away to show the harp frame and improved mounting means securing the shade thereon;

Fig. 2 is a cross-sectional view of parts of the improved mounting means taken along the line 22 of Fig. 1;

Fig. 3 is a cross-sectional view similar to that of Fig. 2 but taken 90 degrees removed about the vertical axis;

Fig. 4 is a bottom view of the improved connecting device, portions of the harp and lamp shade being broken away;

Fig. 5 is a horizontal sectional view taken along the line 5-5 of Fig. 3; and

Fig. 6 is a top partial view of the harp illustrating how the stud member is placed thereon prior to the forming operation for securing it.

Referring now to the drawing, the lamp 10 has mounted thereon a harp frame 11 on which the lamp shade 12 is secured by means of the improved connection device comprising the invention.

The mounting means comprises a stud member 13, a washer 14 and a finial 15. The stud member 13, before being formed over the harp 11, as herein below described, comprises a flat, oval-shaped base 16 having a pair of opposed semi-circular cut-out portions 17, 18 the centers of which lie along the greater diameter of said base. A threaded stud portion 19 extends outwardly at right angles with respect to the base 16 (see Fig. 6).

The top central portion of the harp 11 is double-bent downardly in the shape of a shallow U, the width of this 2,770,718 Patented Nom a, 1956 bent-down portion, indicated by the numeral 20, being such that the base 16 of the stud member 13 can fit snugly therein, its cut-out portions 17, and 18 closely embracing the sides of the bent-down portion 20 thereof. So positioned, the stud member 13 is rigidly secured to the harp by forming the sides of the base 16 about the bent-down portion 20, as is best illustrated in Figs. 2 and 4.

The U-shaped portion 20 has side arms 20a and a bottom web 20b. The base element 16 rests on web 20b and between side arms 20a, and its sides 16a are folded down and, around said web to embrace the same for clamping member 13 thereto, and the member 13 is thus also non-slidably mounted on the cross Wire.

The washer 14 is cylindrical in shape and is provided with an axial stud opening 21. The washer is countersunk at its underside to provide an annular skirt portion 22. The skirt portion has vertically cut therein a pair of opposed slots 23, 24. Fixed to the washer 14 in any convenient manner are the radially-extending spider arms 25, the ends of which are fixed to the usual wire loop comprising the upper portion of the lamp shade frame. It will thus be evident that the washer 13 is centrally fixed width respect to the shade 12.

In use, the shade 12 is placed over the harp 11 so that the stud portion 19 of the stud member 13 extends through the stud opening 21 of the washer 14, and then rotated until the slots 23, 24 fall over the harp 11. The usual vertically-drilled and tapped finial is then screwed upon the stud portion 19 to hold the lamp shade securely in place. It is to be noted that the shade so secured can neither be rotated, because the harp is confined in the slots 23, 24 of the washer 14, nor tilted, for the reason that the stud member, in accordance with the invention, is so secured to the harp that it cannot be rotated or otherwise moved in any direction with respect thereto.

It will be understood that changes in the details of the structure illustrated and described will occur to those skilled in the art without departing from the spirit and purpose of my invention.

Hence, it is my intention to cover by claims appended hereto any modified or equivalent structure which may be reasonably included within their scope.

I claim:

1. In combination, a lamp harp frame having a cross wire, a downwardly extending U-shaped intermediate portion in said cross Wire having side arms connected by a Web, and a connection for mounting a lamp shade on the cross wire, said connection comprising a first member and a second member, said first member having a base element, a threaded stud extending up from said base element, said base element resting on and being formed around the web of said U-shaped portion in said cross wire and between the side arms of said U-shaped portion, to clamp said first member on said cross wire, said second member having an opening extending through the center thereof, said threaded stud on the first member being positioned in said opening and extending out therefrom, said second member having downwardly opening slots through the sides thereof to permit said second member to be moved downwardly onto the cross wire, said cross wire being received in said slots on opposite sides of said U-shaped portion whereby the second member is seated on the cross wire and. over the base element of the first member, and a finial screw on said threaded stud for securing said first and second members together, said base member being provided with a pair of opposed cut-out portions embracing the inner surfaces of the side arms of said U-shaped portion.

2. In combination, a lamp harp frame having a cross wire, a downwardly extending U-shaped intermediate portion in said cross wire having side arms connected by a web, and a connection for mounting a lamp shade on the cross wire, said connection comprising a first member and a second member, said first member having a base element, a threaded stud extending up from said base element, said base element resting on and being formed around the web of said U-shaped portion in said cross wire and between the side arms of said U-shaped portion, to clamp said first member on said cross wire, said second member having an opening extending through the centerthereof, said threaded stud on the first member being' positioned in said opening and extending out therefrom, said second member having downwardiy opening slots through the sides thereof to permit said second member to be moved downwardly onto the cross wire, said cross wire being received in said slots on opposite sides of said U-shaped portion whereby the second member is seated on the cross wire and over the base element of the first member, and a finial screw on saidthreaded stud for securing said first and second members'together, said base element being of oval shape prior to being formed around said U-shaped portion.
